YouTube Tuesday: Hydrophonia

NOAA scientists used an under water microphone — a hydrophone — to capture audio of the massive earthquake that hit Japan a few weeks ago.

You may have heard of it. It was in the news and everything.

Now the full force of mother nature can be terrifyingly relived as scientists from the Pacific Marine Environmental Laboratory in Seattle have released an extraordinary recording of the sound of the 9.0 earthquake as it powered its way through the Pacific ocean moments before creating the devastating tsunami.

Captured by an underwater microphone called a hydrophone positioned 900 miles away from the epicentre in the Aleutian Islands in Alaska the earthquake's incredible rumbling and roaring is not dissimilar to the sound of a rocket taking off.
